The acetate esters present in the compound will allow the tribnabol to initiate a rapid change in the physiology initially. This is because it elevates the blood plasma levels. The other two esters that are the trenbolone hexahydrobenzylcarbonate and trenbolone enanthate present in Tri Tren 150 are often released at a slower rate. This will prolong the impact of the initial physiology. As trenbolone itself is a strong androgen, this extended effect on the blood plasma levels will increase the mass of the body.
